  Green Screen?

  From Wikipedia link: http://en.wikipedia.org/wiki/Chroma_key Green is currently used as a backdrop more than any other color because image sensors in cameras are most sensitive to green. Therefore the green camera channel contains the least “noise” and can produce the cleanest key/matte/mask. Additionally, less light is needed to illuminate green because of the higher sensitivity to green in the image sensors.[4] Blue was used before digital keying became commonplace because it was necessary for the optical process, but it needed more illumination than green.

  Any recomendation for entry level DSLR?

  I bought my first DSLR last November: Canon Rebel XSi (aka 450D), the latest in their line of entry-level DSLRs. This model improves many shortcomings of the earlier versions (XTi, XT). The picture quality is outstanding, though I wish I could afford one of their high-end “L-Series” lenses. (someday…) I was torn between this model and the Nikon D90. In the end, I chose to save money with the Canon. I’m very happy with the camera – excellent photo quality, good blend of features and ease-of-use, and enough performance to keep up with an active 6-year-old son. Mine came with a “kit” zoom lens. I added a 50mm Prime (non-zoom) lens, a more powerful flash unit (430EX-II), and a set of adapters to use my telescope as a 1800mm lens. At this point, I’ve spent close to $1000 US, so I guess I can’t call it an entry-level purchase. The true entry-level models would be the Canon Rebel XS and either the Nikon D40 or D60. I can recommend the site http://dpreview.com for reviews, though it is somewhat technical.

  If you walk past a mirror, do you usually stop and check yourself out?

  I check for one critical issue: Do I have any lettuce stuck in my teeth?

  Do you find it offensive when a person "witnesses" to you?

  The best advice I’ve ever heard on this topic is: There are few things people hate more than answers to questions they didn’t ask. Seems apropos to mention on fluther, somehow… Funny how the word fluther fails the spell check…

  Do ergonomic keyboards really help?

  I have found that split keyboards, like the M$ Ergonomic 4000 (or the wireless 7000 set) work great for me when I am typing 4–6 hours a day. However, there are things you can do to make your existing keyboard easier on your wrists. First, don’t raise the feet at the rear of the keyboard, as this forces you to bend your wrists even further in the wrong direction. Make the keyboard as flat as possible, or even reverse-tilt (up to 7 degrees), to allow your wrists to rest in a more natural position. Second, consider an adjustable (articulating) keyboard tray, which will allow you to position the keyboard closer to your lap and adjust the tilt precisely. Third, as already mentioned, frequent breaks are essential. While my experience with split ergonomic keyboards has been good, I have learned that what works for me can be intolerable to others. Be prepared to return one or two for a refund before you find one that works for you. I hope this helps.
